Tags Share this article 6/14/16 Published Hospitals are increasingly becoming a favored target of cyber criminals. Yet if you think about medical equipment that is vulnerable to being hacked at a hospital, you might not immediately think of high-end, critical equipment such as MRI and X-ray scanners, and nuclear medicine devices. After all, these devices go through rigorous approval processes by the US Food & Drug Administration (FDA) before they are approved for safe use on patients. Yet today many, if not most, medical devices, have computers embedded in them, are connected to the hospital network, and often to the internet as well, so they provide a potential attack vector for cyber criminals. In late 2015 security researchers found that thousands of medical devices were vulnerable to attack and exposed to the public Internet. Interestingly, these researchers also found that many of the devices in question were running Windows XP – which is no longer supported or updated by Microsoft – and did not run antivirus software to protect them against malware. This combination raises an obvious security red flag. Ironically, these security vulnerabilities were further exacerbated because of the very FDA approvals process that certifies the devices. The approval process is, quite rightly, extremely rigorous. It is also lengthy and expensive. And if a manufacturer or vendor makes a change to a device, it needed to be re-certified. Until very recently, a ‘change’ to a medical device meant any sort of change – including patching devices’ operating systems and firmware to close off potential network security vulnerabilities. You can see where this is going: making simple updates to medical equipment to improve its defenses against cyberattacks was made that much more difficult and complex for the device manufacturers, because of the need for FDA re-certification every time a change was made. And of course, this potential delay in patching vulnerabilities made it easy for a hacker to try and ‘update’ the device in his own way, for criminal purposes. Hackers are usually not too concerned about getting FDA approval for their work. Fortunately, the FDA released new guidelines last year that allowed equipment manufacturers to patch software as required without undergoing re-certification—provided the change or modification does not ‘significantly affect the safety or effectiveness of the medical device’. That’s good news – but it’s not quite the end of the story. The FDA’s guidelines are only a partial panacea to the overall problem. They overlook the fact that many medical devices are running obsolete operating systems like Windows XP. What’s more, the actual process of applying patches to the computers in medical devices can vary enormously from manufacturer to manufacturer, with some patches needing to be downloaded and applied manually, while others may be pushed automatically. In either case, there could still be a window of weeks, months or even years before the device’s vendor issues a patch for a given vulnerability – a window that a hacker could exploit before the hospital’s IT team becomes aware that the vulnerability exists. This means that hospitals need to take great care when it comes to structuring and segmenting their network . It is vital that connected medical devices – particularly those where the internal OS may be out of date – are placed within defined, segregated segments of the network, and robustly protected with next-generation firewalls, web proxies and other filters. While network segmentation and filtering will not protect unpatched or obsolete operating system, they will ensure that the hospital’s network is secured to the best of its ability .

At a time when many organizations are moving their resources to the cloud and security threats are at an all-time high, focusing on your cloud security architecture has never been more critical. While cloud adoption has revolutionized businesses, it has also brought complex challenges. For example, cloud environments can be susceptible to numerous security threats. Besides, there are compliance regulations that you must address. This is why it’s essential to implement the right methods, frameworks, and best practices in cloud environments. Doing so can protect your organization’s sensitive cloud resources, help you meet compliance regulations, and maintain customer trust. Understanding Cloud Security Architecture Cloud security architecture is the umbrella term that covers all the hardware, software, and technologies used to protect your cloud environment. It encompasses the configurations and secure activities that protect your data, workloads, applications, and infrastructure within the cloud. This includes identity and access management (IAM), application and data protection, compliance monitoring, secure DevOps, governance, and physical infrastructure security. A well-defined security architecture also enables manageable decompositions of cloud deployments, including mixed SaaS, PaaS, and IaaS deployments. This helps you highlight specific security needs in each cloud area. Additionally, it facilitates integration between clouds, zones, and interfaces, ensuring comprehensive coverage of all deployment aspects. Cloud security architects generally use a layered approach when designing cloud security. Not only does this improve security, but it also allows companies to align business needs with technical security practices. As such, a different set of cloud stakeholders, including business teams and technical staff, can derive more value. The Fundamentals of Cloud Security Architecture Every cloud computing architecture has three core fundamental capabilities; confidentiality, integrity, and availability. This is known as the CIA triad. Understanding each capability will guide your efforts to build, design, and implement safer cloud environments. 1. Confidentiality This is the ability to keep information hidden and inaccessible to unauthorized entities, such as attackers, malware, and people in your organization, without the appropriate access level. Privacy and trust are also part of confidentiality. When your organization promises customers to handle their data with utmost secrecy, you’re assuring them of confidentiality. 2. Integrity Integrity means that the services, systems, and applications work and behave exactly how you expect. That is, their output is consistent, accurate, and trustworthy. If these systems and applications are compromised and produce unexpected or misleading results, your organization may suffer irreparable damage. 3. Availability As the name implies, availability assures your cloud resources are consistently accessible and operational when needed. So, suppose an authorized user (whether customers or employees) needs data and applications in the cloud, such as your products or services. In that case, they can access it without interruption or significant downtime. Cybercriminals sometimes use denial-of-service (DoS) attacks to prevent the availability of cloud resources. When this happens, your systems become unavailable to you or your customers, which isn’t ideal. So, how do you stop that from happening and ensure your cloud security architecture provides these core capabilities? Approaches to Cloud Security Architecture There are multiple security architecture approaches, including frameworks and methodologies, to support design and implementation steps. Cloud Security Frameworks and Methodologies A cloud security framework outlines a set of guidelines and controls your organizations can use when securing data, applications, and infrastructures within the cloud computing environment. Frameworks provide a structured approach to detecting risks and implementing appropriate security protocols to prevent them. Without a consistent cloud security framework, your organization exposes itself to more vulnerabilities. You may lack the comprehensive visibility to ensure your data and applications are adequately secure from unauthorized access, data exposure, malware, and other security threats. Plus, you may have limited incident response capabilities, inconsistent security practices, and increased operational risks. A cloud security framework also helps you stay compliant with regulatory requirements. Lastly, failing to have appropriate security frameworks can erode customer trust and confidence in your ability to protect their privacy. This is why you must implement a recognized framework to significantly reduce potential risks associated with cloud security and ensure the CIA of data and systems. There are numerous security frameworks. Some are for governance (e.g., COBIT and COSO), architecture (e.g., SABSA), and the NIST cybersecurity framework. While these generally apply broadly to technology, they may also apply to cloud environments. Other cloud-specific frameworks include the ISO/IEC 27017:2015, Cloud Control Matrix (CCM), Cloud Security Alliance, and the FedRAMP. 1. NIST Cybersecurity Framework (NIST CSF) The National Institute of Standards and Technology’s Cybersecurity Framework (NIST CSF) outlines a set of guidelines for securing security systems. It has five core capabilities: Identify, Protect, Detect, Respond, and Recover. Identify – What processes, assets, and systems need protection? Protect – Develop and implement the right safeguards to ensure critical infrastructure services delivery. Detect – Implement the appropriate mechanisms to enable the timely discovery of cybersecurity incidents. Respond – Develop techniques to contain the impact of potential cybersecurity incidents. Recover – Implement appropriate measures to restore business capabilities and services affected by cybersecurity events. While the NIST CSF is a general framework for the security of your organization’s systems, these five pillars can help you assess and manage cloud-related security risks. 2. ISO/IEC 27017:2015 ISO 27017 is a cloud security framework that defines guidelines on information security issues specific to the cloud. The framework’s security controls add to the ISO/IEC 27002 and ISO/IEC 27001 standards’ recommendations. The framework also offers specific security measures and implementation advice for cloud service providers and applications. 3. Sherwood Applied Business Security Architecture (SABSA) First developed by John Sherwood, SABSA is an Enterprise Security Architecture Framework that provides guidelines for developing business-driven, risk, and opportunity-focused security architectures to support business objectives. The SABSA framework aims to prioritize your business needs, meaning security services are designed and developed to be an integral part of your business and IT infrastructure. Here are some core principles of the Gartner-recommended SABSA framework for enterprises: It is business-driven. SABSA ensures security is integrated into your entire business strategy. This means there’s a strong emphasis on understanding your organization’s business objectives. So, any security measure is aligned with those objectives. SABSA is a risk-based approach. It considers security vulnerabilities, threats, and their potential impacts to prioritize security operations and investments. This helps your organization allocate resources effectively to address the most critical risks first. It promotes a layered security architecture. Earlier, we mentioned how a layered approach can help you align business and technical needs. So, it’s expected that this is a core principle of SABSA. This allows you to deploy multiple security controls across different layers, such as physical security, network security, application security, and data security. Each layer focuses on a specific security aspect and provides special controls and measures. Transparency: SABSA provides two-way traceability; that is, a clear two-way relationship exists between aligning security requirements and business goals. This provides a clear overview of where expenditure is made ad the value that is returned. Modular approach: SABSA offers agility for ease of implementation and management. This can make your business flexible when meeting changing market or economic conditions. 4. MITRE ATT&CK The MITRE ATT&CK framework is a repository of techniques and tactics that threat hunters, defenders, red teams, and security architects can use to classify, identify, and assess attacks. Instead of focusing on security controls and mechanisms to mitigate threats, this framework targets the techniques that hackers and other threat actors use in the cloud. So, using this framework can be excellent if you want to understand how potential attack vectors operate. It can help you become proactive and strengthen your cloud security posture through improved detection and incident response. 5. Cloud Security Alliance Cloud Controls Matrix (CSA CCM) The CSA CCM is a cybersecurity control framework specifically for cloud computing. It contains 197 control objectives structured in 17 domains that cover every critical aspect of cloud technology. Cloud customers and cloud service providers (CSPs) can use this tool to assess cloud implementation systematically. It also guides customers on the appropriate security controls for implementation by which actor in the cloud supply chain. 6. Cloud Security Alliance Security Trust Assurance and Risk (CSA STAR) The CSA STAR framework is for CSPs. It combines the principles of transparency, thorough auditing, and harmonization of standards. What CSA STAR does is to help you, as a cloud customer, assess a cloud service provider’s reliability and security posture. There are two ways this can happen: CSA STAR Certification: This is a rigorous third-party assessment of the CSP’s security controls, posture, and practices. The CSP undergoes a thorough audit based on the CSA’s Cloud Control Matrix (CCM), which is a set of cloud security controls aligned with industry standards. CSA STAR Self-Assessment: The CSA also has a Consensus Assessment Initiative Questionnaire (CAIQ). CSPs can use this to test and report on their security controls and practices. Since it’s a self-assessment procedure, it allows CSPs to be transparent, enabling customers like you to understand a CSP’s security capabilities before adopting their services. Challenges and Considerations in Cloud Security Architecture Before any cloud deployment, it’s important to understand the threats you may face, such as privilege-based attacks and malware, and be prepared for them. Since there are many common threats, we’ll quickly run through the most high-profile ones with the most devastating impacts. It’s important to remember some threats may also be specific to the type of cloud service model. 1. Insider risks This includes the employees in your organization who have access to data, applications, and systems, as well as CSP administrators. Whenever you subscribe to a CSP’s services, you entrust your workloads to the staff who maintain the CSP architecture. 2. DoS attacks Direct denial-of-service (DDoS) attacks are critical issues in cloud environments. Although security perimeters can deflect temporary DDoS attacks to filter out repeated requests, permanent DoS attacks are more damaging to your firmware and render the server unbootable. If this happens, you may need to physically reload the firmware and rebuild the system from the ground up, resulting in business downtime for weeks or longer. 3. Data availability You also want to consider how much of your data is accessible to the government. Security professionals are focusing on laws and examples that demonstrate when and how government authorities can access data in the cloud, whether through legal processes or court rulings. 4. Cloud-connected Edge Systems The concept of “cloud edge” encompasses both edge systems directly connected to the cloud and server architecture that is not directly controlled by the cloud service provider (CSP). To extend their services to smaller or remote locations, global CSPs often rely on partners as they cannot have facilities worldwide. Consequently, CSPs may face limitations in fully regulating hardware monitoring, ensuring physical box integrity, and implementing attack defenses like blocking USB port access. 5. Hardware Limitations Having the most comprehensive cloud security architecture still won’t help you create stronger passwords. While your cloud security architects focus on the firmware, hardware, and software, it’s down to the everyday users to follow best practices for staying safe. Best Practices in Cloud Security Architecture The best practices in Cloud Security Architecture are highlighted below: 1. Understand the shared responsibility model Cloud security is implemented with a shared responsibility model. Although, as the cloud customer, you may have most of the obligation, the cloud provider also shares some of the responsibility. Most vendors, such as Amazon Web Services (AWS) and Microsoft Azure, have documentation that clearly outlines your specific responsibilities depending on the deployment type. It’s important to clearly understand your shared responsibility model and review cloud vendor policies. This will prevent miscommunications and security incidents due to oversight. 2. Secure network design and segmentation This is one of the principles of cloud security architecture – and by extension, a best practice. Secure network design and segmentation involve dividing the network into isolated segments to avoid lateral movements during a breach. Implementing network segmentation allows your organization to contain potential risks and attacks within a specific segment. This can minimize the effects of an incident on your entire network and protect critical assets within the cloud infrastructure. 3. Deploy an Identity and access management (IAM) solution Unauthorized access is one of the biggest problems facing cloud security. Although hackers now use sophisticated tools to gain access to sensitive data, implementing a robust identity and access management (IAM) system can help prevent many threats. Consider access policies like role-based access control (RBAC) permissions, multi-factor authentication (MFA), and continuous threat monitoring. 4. Consider a CASB or Cloud Security Solution (e.g., Cloud-Native Application Protection (CNAPP) and Cloud Workload Protection Platforms (CWPP) Cloud Access Security Brokers (CASBs) provide specialized tools to enforce cloud security policies. Implementing a CASB solution is particularly recommended if you have a multi-cloud environment involving different vendors. Since a CASB acts as an intermediary between your organization’s on-premise infrastructure and CSPs, it allows your business to extend security policies and controls to the cloud. CASBs can enhance your data protection through features like data loss prevention, tokenization, and encryption. Plus, they help you discover and manage shadow IT through visibility into unauthorized cloud services and applications. Besides CASB solutions, you should also consider other solutions for securing your cloud environments. This includes cloud-native application protection (CNAPP) and cloud workload protection platforms (CWPP). For example, a CNAPP like Prevasio can improve your cloud security architecture with tailored solutions and automated security management. 5. Conduct Audits, Penetration Testing, and Vulnerability Testing Whether or not you outsource security, performing regular penetration tests and vulnerability is necessary. This helps you assess the effectiveness of your cloud security measures and identify potential weaknesses before hackers exploit them. You should also perform security audits that evaluate cloud security vendors’ capabilities and ensure appropriate access controls are in place. This can be achieved by using the guidelines of some frameworks we mentioned earlier, such as the CSA STAR. 6. Train Your Staff Rather than hiring new hires, training your current staff may be beneficial. Your employees have been at your company for a while and are already familiar with the organization’s culture, values, and processes. This could give them an advantage over new hires. As most existing IT skills can be reused, upskilling employees is more efficient and may help you meet the immediate need for a cloud IT workforce. Train your staff on recognizing simple and complex cybersecurity threats, such as creating strong passwords, identifying social engineering attacks, and advanced topics like risk management. 7. Mitigate Cloud Misconfigurations A misconfigured bucket could give access to anyone on the internet. To minimize cloud misconfigurations and reduce security risks, managing permissions in cloud services carefully is crucial. Misconfigurations, such as granting excessive access permissions to external users, can enable unauthorized access and potential data breaches. Attackers who compromise credentials can escalate their privileges, leading to further data theft and broader attacks within the cloud infrastructure. Therefore, it is recommended that IT, storage, or security teams, with assistance from development teams, personally configure each cloud bucket, ensuring proper access controls and avoiding default permissions. 8. Ensure compliance with regulatory requirements Most organizations today need to comply with strict regulatory requirements. This is especially important if you collect personally identifiable information (PII) or if your business is located in certain regions. Before you adopt a new cloud computing service, assess their compliance requirements and ensure they can fulfill data security needs. Failure to meet compliance requirements can lead to huge penalties. Other best practices for your cloud security include continuous monitoring and threat intelligence, data encryption at rest and in transit, and implementing intrusion detection and intrusion prevention systems. Conclusion When establishing a robust cloud security architecture, aligning business objectives and technical needs is important. Your organization must understand the shared responsibility model, risks, the appropriate implementation framework, and best practices. However, designing and developing cloud computing architectures can be complicated. Prevasio can secure your multi-cloud environment in minutes.

Firewall Policy Management 12 Best Network Security Audit Tools + Key Features Asher Benbenisty 2 min read Asher Benbenisty Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 10/25/23 Published Fortified network security requires getting a variety of systems and platforms to work together. Security teams need to scan for potential threats, look for new vulnerabilities in the network, and install software patches in order to keep these different parts working smoothly. While small organizations with dedicated cybersecurity teams may process these tasks manually at first, growing audit demands will quickly outpace their capabilities. Growing organizations and enterprises rely on automation to improve IT security auditing and make sure their tech stack is optimized to keep hackers out. Network Security Audit Tools Explained Network Security Audit Tools provide at-a-glance visibility into network security operations and infrastructure. They scan network security tools throughout the environment and alert administrators of situations that require their attention. These situations can be anything from emerging threats, newly discovered vulnerabilities, or newly released patches for important applications. Your network security audit tools provide a centralized solution for managing the effectiveness of your entire security tech stack – including cloud-based software solutions and on-premises tools alike. With such a wide set of responsibilities, it should come as no surprise that many audit tools differ widely from one another. Some are designed for easy patch management while others may focus on intrusion detection or sensitive data exfiltration. Major platforms and operating systems may even include their own built-in audit tools. Microsoft Windows has an audit tool that focuses exclusively on Active Directory. However, enterprise security teams don’t want to clutter their processes with overlapping tools and interfaces – they want to consolidate their auditing tools onto platforms that allow for easy management and oversight. Types of Network Security Audit Tools Firewall Auditing Tools Firewall security rules provide clear instructions to firewalls on what kind of traffic is permitted to pass through. Firewalls can only inspect connections they are configured to detect . These rules are not static , however. Since the cybersecurity threat landscape is constantly changing, firewall administrators must regularly update their policies to accommodate new types of threats. At the same time, threat actors who infiltrate firewall management solutions can gain a critical advantage over their targets. They can change the organization’s security policies to ignore whatever malicious traffic they are planning on using to compromise the network. If these changes go unnoticed, even the best security technologies won’t be able to detect or respond to the threat. Security teams must regularly evaluate their firewall security policies to make sure they are optimized for the organization’s current risk profile. This means assessing the organization’s firewall rules and determining whether it is meeting its security needs. The auditing process may reveal overlapping rules, unexpected configuration changes , or other issues. Vulnerability Scanners Vulnerability scanners are automated tools that create an inventory of all IT assets in the organization and scan those assets for weak points that attackers may exploit. They also gather operational details of those assets and use that information to create a comprehensive map of the network and its security risk profile. Even a small organization may have thousands of assets. Hardware desktop workstations, laptop computers, servers, physical firewalls, and printers all require vulnerability scanning. Software assets like applications , containers, virtual machines, and host-based firewalls must also be scanned. Large enterprises need scanning solutions capable of handling enormous workloads rapidly. These tools provide security teams with three key pieces of information: Weaknesses that hackers know how to exploit . Vulnerability scanners work based on known threats that attackers have exploited in the past. They show security teams exactly where hackers could strike, and how. The degree of risk associated with each weakness . Since scanners have comprehensive information about every asset in the network, they can also predict the damage that might stem from an attack. This allows security teams to focus on high-priority risks first. Recommendations on how to address each weakness . The best vulnerability scanners provide detailed reports with in-depth information on how to mitigate potential threats. This gives security personnel step-by-step information on how to improve the organization’s security posture. Penetration Testing Tools Penetration testing allows organizations to find out how resilient their assets and processes might be in the face of an active cyberattack. Penetration testers use the same tools and techniques hackers use to exploit their victims, showing organizations whether their security policies actually work. Traditionally, penetration testing is carried out by two teams of cybersecurity professionals. The “red team” attempts to infiltrate the network and access sensitive data while the “blue team” takes on defense. Cybersecurity professionals should know how to use the penetration testing tools employed by hackers and red team operatives. Most of these tools have legitimate uses and are a fixture of many IT professionals’ toolkits. Some examples include: Port scanners . These identify open ports on a particular system. This can help users identify the operating system and find out what applications are running on the network. Vulnerability scanners . These search for known vulnerabilities in applications, operating systems, and servers. Vulnerability reports help penetration testers identify the most reliable entry point into a protected network. Network analyzers . Also called network sniffers, these tools monitor the data traveling through the network. They can provide penetration testers with information about who is communicating over the network, and what protocols and ports they are using. These tools help security professionals run security audits by providing in-depth data on how specific attack attempts might play out. Additional tools like web proxies and password crackers can also play a role in penetration testing, providing insight into the organization’s resilience against known threats. Key Functionalities of Network Security Audit Software Comprehensive network security audit solutions should include the following features: Real-time Vulnerability Assessment Network Discovery and Assessment Network Scanning for Devices and IP Addresses Identifying Network Vulnerabilities Detecting Misconfigurations and Weaknesses Risk Management Customizable Firewall Audit Templates Endpoint Security Auditing Assessing Endpoint Security Posture User Account Permissions and Data Security Identifying Malware and Security Threats Compliance Auditing Generating Compliance Audit Reports Compliance Standards and Regulations PCI DSS HIPAA GDPR NIST Integration and Automation with IT Infrastructure Notifications and Remediation User Interface and Ease of Use Operating System and Configuration Auditing Auditing Windows and Linux Systems User Permissions and Access Control Top 12 Network Security Audit Tools 1.

Steps to Conduct a Network Security Audit Define the Scope : Start by defining the scope of your audit. You’ll need to determine which parts of your network and systems will be audited. Consider the goals and objectives of the audit, such as identifying vulnerabilities, ensuring compliance, or assessing overall security posture. Gather Information : Collect all relevant information about your network, including network diagrams, asset inventories, and existing security policies and procedures. This information will serve as a baseline for your audit. The more comprehensive this information is, the more accurate your audit results can be. Identify Assets : List all the assets on your network, including servers, routers, switches, firewalls, and endpoints. Ensure that you have a complete inventory of all devices and their configurations. If this information is not accurate, the audit may overlook important gaps in your security posture. Assess Vulnerabilities : Use network vulnerability scanning tools to identify vulnerabilities in your network. Vulnerability scanners like Nessus or OpenVAS can help pinpoint weaknesses in software, configurations, or missing patches. This process may take a long time if it’s not supported by automation. Penetration Testing : Conduct penetration testing to simulate cyberattacks and assess how well your network defenses hold up. Penetration testing tools like Metasploit or Burp Suite can help identify potential security gaps. Automation can help here, too – but the best penetration testing services emulate the way hackers work in the real world. Review Policies and Procedures : Evaluate the results of your vulnerability and penetration testing initiatives. Review your existing security policies and procedures to ensure they align with best practices and compliance requirements. Make necessary updates or improvements based on audit findings. Log Analysis : Analyze network logs to detect any suspicious or unauthorized activities. Log analysis tools like Splunk or ELK Stack can help by automating the process of converting log data into meaningful insights. Organizations equipped with SIEM platforms can analyze logs in near real-time and continuously monitor their networks for signs of unauthorized behavior. Review Access Controls : Ensure the organization’s access control policies are optimal. Review user permissions and authentication methods to prevent unauthorized access to critical resources. Look for policies and rules that drag down production by locking legitimate users out of files and folders they need to access. Firewall and Router Configuration Review: Examine firewall and router configurations to verify that they are correctly implemented and that access rules are up to date. Ensure that only necessary ports are open, and that the organization’s firewalls are configured to protect those ports. Prevent hackers from using port scanners or other tools to conduct reconnaissance. Patch Management : Check for missing patches and updates on all network devices and systems. Regularly update and patch software to address known vulnerabilities. Review recently patched systems to make sure they are still compatible with the tools and technologies they integrate with. Incident Response Plan : Review and update your incident response plan. Ensure the organization is prepared to respond effectively to security incidents, and can rely on up-to-date playbooks in the event of a breach. Compare incident response plans with the latest vulnerability scanning data and emerging threat intelligence information. Documentation and Reporting: Document all audit findings, vulnerabilities, and recommended remediation steps. Generate data visualizations that guide executives and other stakeholders through the security audit process and explain its results. Create a comprehensive report that includes an executive summary, technical details, and prioritized action items. Remediation : Implement the necessary changes and remediation measures to address the identified vulnerabilities and weaknesses. Deploy limited security resources effectively, prioritizing fixes based on their severity. Avoid unnecessary downtime when reconfiguring security tools and mitigating risk. Follow-Up Audits: Schedule regular follow-up audits to ensure that the identified vulnerabilities have been addressed and that security measures are continuously improved. Compare the performance metric data gathered through multiple audits and look for patterns emerging over time. Training and Awareness: Provide training and awareness programs for employees to enhance their understanding of security best practices and their role in maintaining network security. Keep employees well-informed about the latest threats and vulnerabilities they must look out for. FAQs What are some general best practices for network security auditing? Network security audits should take a close look at how the organization handles network configuration management over time. Instead of focusing only on how the organization’s current security controls are performing, analysts should look for patterns that predict how the organization will perform when new threats emerge in the near future. This might mean implementing real-time monitoring and measuring how long it takes for obsolete rules to get replaced. What is the ideal frequency for conducting network security audits? Network security audits should be conducted at least annually, with more frequent audits recommended for organizations with high-security requirements. Automated policy management platforms like AlgoSec can help organizations audit their security controls continuously. Are network security audit tools effective against zero-day vulnerabilities? Network security audit tools may not detect zero-day vulnerabilities immediately. However, they can still contribute by identifying other weaknesses that could be exploited in tandem with a zero-day vulnerability. They also provide information on how long it takes the organization to recognize new vulnerabilities once they are discovered. What should I look for when choosing a network security audit tool for my organization? Consider factors like the tool’s compatibility with your network infrastructure, reporting capabilities, support and updates, and its track record in identifying vulnerabilities relevant to your industry. Large enterprises highly value scalable tools that support automation. Can network security audit tools help with regulatory compliance? Yes, many audit tools offer compliance reporting features, helping organizations adhere to various industry and government regulations. Without an automated network security audit tool in place, many organizations would be unable to consistently demonstrate compliance. How long does it take to conduct a typical network security audit? The duration of an audit varies depending on the size and complexity of the network. A thorough audit can take anywhere from a few days to several weeks. Continuous auditing eliminates the need to disrupt daily operations when conducting audits, allowing security teams to constantly improve performance. What are the most common mistakes organizations make during network security audits? Common mistakes include neglecting to update audit tools regularly, failing to prioritize identified vulnerabilities, and not involving key stakeholders in the audit process. Overlooking critical assets like third-party user accounts can also lead to inaccurate audit results. What are some important capabilities needed for a Cloud-Based Security Audit? Cloud-based security audits can quickly generate valuable results by scanning the organization’s cloud-hosted IT assets for vulnerabilities and compliance violations. However, cloud-based audit software must be able to recognize and integrate third-party SaaS vendors and their infrastructure. Third-party tools and platforms can present serious security risks, and must be carefully inspected during the audit process. What is the role of Managed Service Providers (MSPs) in Network Security Auditing? MSPs can use audits to demonstrate the value of their services and show customers where improvement is needed. Since this improvement often involves the customer drawing additional resources from the MSP, comprehensive audits can improve the profitability of managed service contracts and deepen the connection between MSPs and their customers.

Hybrid Cloud Security Management Six best practices for managing security in the hybrid cloud Omer Ganot 2 min read Omer Ganot Short bio about author here Lorem ipsum dolor sit amet consectetur.

Tags Share this article 8/5/21 Published Omer Ganot, Cloud Security Product Manager at AlgoSec, outlines six key things that businesses should be doing to ensure their security in a hybrid cloud environment Over the course of the past decade, we’ve seen cloud computing vastly transitioning from on-prem to the public cloud. Businesses know the value of the cloud all too well, and most of them are migrating their operations to the cloud as quickly as possible, particularly considering the pandemic and the push to remote working. However, there are major challenges associated with transitioning to the cloud, including the diversity and breadth of network and security controls and a dependency on legacy systems that can be difficult to shake. Public cloud allows organizations for better business continuity, easier scalability and paves the way for DevOps to provision resources and deploy projects quickly. But, what’s the security cost when looking at the full Gpicture of the entire hybrid network? Here I outline the six best practices for managing security in the hybrid cloud: 1. Use next-generation firewalls Did you know that almost half (49%) of businesses report running virtual editions of traditional firewalls in the cloud? It’s becoming increasingly clear that cloud providers’ native security controls are not enough, and that next-gen firewall solutions are needed. While a traditional stateful firewall is designed to monitor incoming and outgoing network traffic, a next-generation firewall (NGFW) includes features such as application awareness and control, integrated breach prevention and active threat intelligence. In other words, while a traditional firewall will allow for layer 1-2 protection, NGFWs allow for protection from levels 3 through 7. 2. Use dynamic objects On-premise security tends to be easier because subnets and IP addresses are typically static. In the cloud, however, workloads are dynamically provisioned and decommissioned, IP addresses change, so traditional firewalls simply cannot keep up. NGFW dynamic objects allow businesses to match a group of workloads using cloud-native categories, and then use these objects in policies to properly enforce traffic and avoid the need to frequently update the policies. 3. Gain 360-degree visibility As with any form of security, visibility is critical. Without that, even the best preventative or remedial strategies will fall flat. Security should be evaluated both in your cloud services and in the path from the internet and data center clients. Having one single view over the entire network estate is invaluable when it comes to hybrid cloud security. AlgoSec’s powerful AutoDiscovery capabilities help you understand the network flows in your organization. You can automatically connect the recognized traffic flows to the business applications that use them and seamlessly manage the network security policy across your entire hybrid estate. 4. Evaluate risk in its entirety Too many businesses are guilty of only focusing on cloud services when it comes to managing security. This leaves them inherently vulnerable on other network paths, such as the ones that run from the internet and data centers towards the services in the cloud. As well as gaining 360-degree visibility over the entire network estate, businesses also need to be sure to actively monitor those areas for risk with equal weighting in terms of priority. 5. Clean up cloud policies regularly The cloud security landscape changes at a faster rate than most businesses can realistically keep up with. For that reason, cloud security groups tend to change with the wind, constantly being adjusted to account for new applications. If a business doesn’t keep on top of its cloud policy ‘housekeeping’, they’ll soon become bloated, difficult to maintain and risky. Keep cloud security groups clean and tidy so they’re accurate, efficient and don’t expose risk. 6. Embrace DevSecOps The cloud might be perfect for DevOps in terms of easy and agile resource and security provisioning using Infrastructure-as-code tools, but the methodology is seldom used for risk analysis and remediation recommendations. Businesses that want to take control of their cloud security should pay close attention to this. Before a new risk is introduced, you should obtain an automatic what-if risk check as part of the code’s pull request, before pushing to production. From visibility and network management right through to risk evaluation and clean-up, staying secure in a hybrid cloud environment might sound like hard work, but by embracing these fundamental practices your organization can start putting together the pieces of its own security puzzle. The AlgoSec Security Management Suite (ASMS) makes it easy to support your cloud migration journey, ensuring that it does not block critical business services and meet compliance requirements.

As the most widely adapted open-source container software, Kubernetes provides businesses with efficient processes to schedule, deploy,... Cloud Security Understanding and Preventing Kubernetes Attacks and Threats Ava Chawla 2 min read Ava Chawla Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 10/20/21 Published As the most widely adapted open-source container software, Kubernetes provides businesses with efficient processes to schedule, deploy, and scale containers across different machines. The bad news is that cybercriminals have figured out how to exploit the platform’s vulnerabilities , resulting in catastrophic network intrusions across many company infrastructures. A recent report revealed that 94% of respondents reported security incidents in Kubernetes environments. The question is, what is behind this surge of Kubernetes attacks, and how can they be prevented? How Kubernetes is Vulnerable As a container-based platform, a new set of vulnerabilities, permission issues, and specific images set the stage for the increase in attacks. The threats have included fileless malware in containers, leveraging misconfigured Docker API ports, and using container images for attacks. Misconfigured Docker API Ports Exploitation Scanning for misconfigured Docker API ports and using them for deploying images containing malware is a relatively new type of attack. The malware, designed to evade static scanning, has become a popular method to hijack compute cycles for fraudulent cryptomining. This cryptojacking activity steals CPU power to mine currencies such as Ethereum and Monero. By first identifying vulnerable front-end websites and other systems, attackers send a command through the application layer simply by manipulating a domain’s text field or through an exposed API in the website’s URL. The code then enters the container, where it is executed with commands sent to a Docker container’s shell. A wget command is executed to download the malware. To protect against this attack, enterprises must ensure their container files are not writable, establish CPU consumption limits, and enable alerts to detect interactive shell launches. DDoS Attacks With Open Docker Daemons Cybercriminals use misconfigured open Docker daemons to launch DDoS attacks using a botnet of containers. UDP flood and Slowloris were recently identified as two such types of container-based botnet attacks. A recent blog describes an anatomy of these Kubernetes attacks. The attackers first identified open Docker daemons using a scanning tool such as Shodan to scan the internet for IP addresses and find a list of hosts, open ports, and services. By uploading their own dedicated images to the Docker hub, they succeeded in deploying and remotely running the images on the host. Analyzing how the UDP flood attack was orchestrated required an inspection of the binary with IDA. This revealed the start_flood and start_tick threads. The source code for the attack was found on Github. This code revealed a try_gb parameter, with the range of 0 to 1,024, used to configure how much data to input to flood the target. However, it was discovered that attackers are able to modify this open-source code to create a self-compiled binary that floods the host with even greater amounts of UDP packets. In the case of the Slowloris attack, cybercriminals launched DDoS with the slowhttptest utility. The attackers were able to create a self-compiling binary that is unidentifiable in malware scans. Protection from these Kubernetes attacks requires vigilant assurance policies and prevention of images other than compliant ones to run in the system. Non-compliant images will then be blocked when intrusion attempts are made. Man in the Middle Attacks With LoadBalancer or ExternalIPs An attack affecting all versions of Kubernetes involves multi-tenant clusters. The most vulnerable clusters have tenants that are able to create and update services and pods. In this breach, the attacker can intercept traffic from other pods or nodes in the cluster by creating a ClusterIP service and setting the spec.externalIP’s field. Additionally, a user who is able to patch the status of a LoadBalancer service can grab traffic. The only way to mitigate this threat is to restrict access to vulnerable features. This can be done with the admission webhook container, externalip-webhook , which prevents services from using random external IPs. An alternative method is to lock external IPs with OPA Gatekeeper with this sample Constraint Templatecan. Siloscape Malware Security researcher, Daniel Prizmant, describes a newer malware attack that he calls Siloscape. Its primary goal is to escape the container that is mainly implemented in Windows server silo. The malware targets Kubernetes through Windows containers to open a backdoor into poorly configured clusters to run the malicious containers. While other malware attacks focus on cryptojacking, the Siloscape user’s motive is to go undetected and open a backdoor to the cluster for a variety of malicious activities. This is possible since Siloscape is virtually undetectable due to a lack of readable strings in the binary. This type of attack can prove catastrophic. It compromises an entire cluster running multiple cloud applications. Cybercriminals can access critical information including sign-ins, confidential files, and complete databases hosted inside the cluster. Additionally, organizations using Kubernetes clusters for testing and development can face catastrophic damage should these environments be breached. To prevent a Siloscape attack, it is crucial that administrators ensure their Kubernetes clusters are securely configured. This will prevent the malware from creating new deployments and force Siloscape to exit. Microsoft also recommends using only Hyper-V containers as a security boundary for anything relying on containerization. The Threat Matrix The MITRE ATT&CK database details additional tactics and techniques attackers are using to infiltrate Kubernetes environments to access sensitive information, mine cryptocurrency, perform DDoS attacks, and other unscrupulous activities. The more commonly used methods are as follows: 1. Kubernetes file compromise Because this file holds sensitive data such as cluster credentials, an attacker could easily gain initial access to the entire cluster. Only accept kubeconfig files from trusted sources. Others should be thoroughly inspected before they are deployed. 2. Using similar pod names Attackers create similar pod names and use random suffixes to hide them in the cluster. The pods then run malicious code and obtain access to many other resources. 3. Kubernetes Secrets intrusion Attackers exploit any misconfigurations in the cluster with the goal of accessing the API server and retrieving information from the Secrets objects. 4. Internal network access Attackers able to access a single pod that communicates with other pods or applications can move freely within the cluster to achieve their goals. 5. Using the writeable hostPath mount Attackers with permissions to create new containers can create one with a writeable hostPath volume. Kubernetes Attacks: Key Takeaways Kubernetes brings many advantages to organizations but also presents a variety of security risks, as documented above. However, by ensuring their environments are adequately protected through proper configuration and appropriately assigned permissions, the threat of Kubernetes attacks is greatly minimized. Should a container be compromised, properly assigned privileges can severely limit a cluster-wide compromise.

Challenge MIND’s complex network consists of many remote locations and is secured with more than 40 firewalls from multiple vendors, including Check Point, Fortinet and Juniper as well as Blue Coat proxies. With hundreds of unnecessary rules in each of the firewalls under management, MIND’s Network Support team members were spending too much time cleaning up the policy rule base. “Cleaning up the policy rule base is a tedious, risky manually-intensive job,” said Santosh Sahoo, Assistant Project Manager at MIND. “Furthermore, we had to evaluate the risks based on best practices or our experience, which was time consuming. We also had to collect and organize this information into the proper reporting format for ISO 27001 requirements.” Additionally, manually planning and implementing firewall changes was a time-consuming and complex process, as was keeping track of all of the changes and updating records for auditing and/or rollback purposes. With all of these challenges, plus increasing network complexity, MIND realized they needed a more efficient method for centrally monitoring and managing all of their security devices and policies. Solution MIND selected the AlgoSec Security Management solution to automate firewall operations across the entire multivendor estate and reduce the resource strain. “There were many reasons why we chose AlgoSec over alternative options. It met all of our requirements by supporting a wider range of devices, providing a dashboard with immediate visibility and more robust policy analysis,” said Harvansh Sagar, GM of IT Infrastructure. Results Since implementing AlgoSec, the MIND team has significantly improved its firewall policy management change processes — from identifying any pre-existing rules in place, to risk assessment, to simulating the change. “AlgoSec has helped us make our our network more secure and has improved our ability to efficiency to manage more client devices with the same resources,” said Sagar. “We are now able to more efficiently analyze the firewall policies, spend less time on repetitive and error-prone manual tasks and perform a risk assessment before approving firewall changes. This automation saves time and man hours by at least five hours per change,” said Santosh. “AlgoSec’s firewall policy analysis has also improved the performance of the firewalls with features like policy tuning, identifying un-used policies and reordering policies.” With AlgoSec, MIND has a complete understanding of what is occurring with the policy across all of their firewalls. “We have a virtual server dedicated to AlgoSec as our management server for all of the firewalls in our environment. It monitors our security policy 24×7 and provides us with real-time alerting for details like ‘who added/modified/removed the rule, what time the policy was pushed,’ etc. Now we have full visibility of what’s going on with these devices,” said Santosh. Using AlgoSec, MIND has also been able to significantly reduce the time to perform audits and ensure compliance. “We can now run an audit report for ISO 27001 out-of-the-box and get a view of the network security policy status in just a click of button.” Schedule time with one of our experts
